North End
South End


Envisioned as a nearly 850 mile route from New Orleans to Kansas City, Interstate 49 is currently signed on four distinct segments from the Gulf Coast to the Midwest. The original 208-mile stretch runs north from Lafayette to Shreveport. Subsequent sections are posted from Blanchard, Louisiana north to Texarkana, between Alma and Bentonville, Arkansas, and between Pineville and Grandview, Missouri. Additional sections, each signed as Arkansas 549, include the Bella Vista Bypass section, around the south and west sides of the city, and the Chaffee Crossing section to the southeast of Fort Smith, Arkansas.

Future Interstate 49 corridor signage appears from Lafayette southeastward via U.S. 90 to New Orleans. Interstate standard upgrading is underway along U.S. 90 near New Iberia and Morgan City, and Interstate 49 will culminate its journey along the Westbank Expressway before terminating at Interstate 10 in Downtown New Orleans. The majority of this section (from Lafayette east to the junction of Interstate 310 and unsigned Interstate 910) was approved as “Future Interstate 49” by AASHTO’s Route Numbering Subcommittee on November 6, 1998. The section between I-310 and I-10 (unsigned I-910) was designated as Future I-49 on October 1, 1999.

High Priority Corridor

Interstate 49 from Shreveport to Kansas City is part of High Priority Corridors 1 and 72: North-South Corridor, while the future section between New Orleans and Lafayette is part of High Priority Corridor 37: U.S. 90.

Construction Progress


Current construction along Interstate 49 South includes a number of projects to convert U.S. 90 into a limited access highway. Within Lafayette Parish, a $57.1 million interchange between U.S. 90 at Ambassador Caffery (LA 3073) is under construction through summer 2018. Work here also includes expanding U.S. 90 to six lanes for 1.6 miles between LA 3073 and building a new overpass joining Albertson Parkway and St. Nazaire Road.39 Work underway in St. Mary Parish adds an interchange with U.S. 90 at Louisiana 318. The two year, $56 million project runs through December 2017.40

Further east at Patterson, a $15-million in federal money funds the construction of J-turns from Ricohoc to Berwick to eliminate crossovers along U.S. 90. The safety measure, expected to start by March 2017, is temporary until state officials can secure funds for the building of permanent overpasses at Red Cypress Road in Patterson, Thorguson Road in Berwick and Southeast Boulevard in Bayou Vista. Frontage roads will connect the cross roads, with a potential interchange added at Tiffany and Lipari Streets in Patterson. Costs are estimated at $250 million for the array of projects.40

The I-49 Lafayette Connector is still under study, with government, business and community leaders collaborating in the planning and conceptual design process. The 1.5 mile freeway link may cost anywhere between $355 million and $688 million based upon what design is selected. Options range from a tunnel, a semi-depressed roadway and two elevated viaducts. 24 design modifications were under study by consultants as of October 2016. The design alternatives are expected to be finalized in Dececember.43

Presently Interstate 49 has a gap between Interstate 20 near Downtown Shreveport and Louisiana 1 to the east of Blanchard. Original plans shifted I-49 onto Louisiana 3132 (Inner Loop Expressway) and the western portion of Interstate 220 to bypass Shreveport. However efforts emerged from the city of Shreveport and local officials to build the I-49 Inner City Connector. The Connector is approximately 3.6 miles in length. If constructed, I-49 will continue north from I-20 along Peter Harris Drive to Ford Street and then northwesterly along Twelvemile Bayou to I-220. A Feasibility Study and Environmental Inventory was completed in May 2010 and currently an Environmental Impact Statement is underway.

Otherwise if I-49 shifts to the bypass, the existing segment of Interstate 49 between the four level interchange at Louisiana 3132 and Interstate 20 will have to be renumbered. Continuation of I-49 North from I-220 will follow Segment K north from a new interchange located one mile to the west of the current interchange (Exit 7) with U.S. 71 and Louisiana 1.1

Work on Segment K, I-49 between I-220 and LA 1 near Blanchard, went to bid in December 2013. This was two years after expected due to funding issues for the $70-100 million project.22,24 It is estimated for completion in 2017-18.25


A half-diamond interchange with U.S. 59 & 71 at the north end of I-49 outside Texarkana, Arkansas will eventually connect with a six to eight mile alignment proposed through Bowie County, Texas. This alignment includes a proposed interchange with Interstate 369.

As of fall 2016, no construction was underway for Interstate 49 between Texarkana and the Fort Smith area. Chamber of Commerce representatives from along the corridor discussed the final stages of completing I-49 in June 2016. The meeting encouraged moving forward on the project, with a focus on building the I-49 bridge over the Arkansas River at Alma and the initiation of right of way acquisition south of Fort Smith.41 The 2016-20 State Transportation Improvement Plan (STIP) included a $27.4 million request for preliminary engineering for the span. Coupled with right of way purchases and utility costs, the Arkansas River bridge is expected to cost more than $235.4 million. Associated work to build 13.81 miles of new road from Arkansas 22 north to Interstate 40 is estimated to cost $235.4 million.41

A second Bella Vista Bypass project was let May 2, 2012. It pertaining to 2.377 miles of two-lane roadway leading north from the AR 72 interchange west of Hiwasse to County Road 34. Work on this section ran through July 2015. A third portion is also underway to extend AR 549 east from AR 72 to U.S. 71 Business in Bella Vista. The 6.36-mile portion is being built at a cost of $52.6-million. It is scheduled for completion in 2017.31


The Interstate 49 corridor will not utilize the Missouri 249 and 171 corridor east of Joplin due to the presence of traffic signals at the diamond interchange between U.S. 71, Missouri 96 and Missouri 171 south.

However three options for consideration in the long term are:17

  • Retain the Interstates 44 & 49 overlap, but upgrade the cloverleaf interchange at Exit 18 into a directional interchange.
  • Utilize the Missouri 249 and 171 corridor by upgrading the interchange between U.S. 71, Missouri 96 and 171.
  • Utilize the Missouri 249 and 171 corridor by construction a new freeway connection from near Morgan Heights northeast to Interstate 49, bypassing Carthage to the north.

A toll road was considered for I-49 from the Bella Vista Bypass in Arkansas north to Pineville,3 but subsequently dropped. The right of way was acquired and plans were completed for the five mile section by 2008. MoDOT was awaiting completion of the Arkansas section to move forward,29 and eventually allocated funding for its portion in the 2013-17 Draft STIP.

The Missouri Highways and Transportation Commission approved the estimated $47.8 million in costs and the timeline to complete the final five miles of the Interstate 49 Missouri-Arkansas Connector on March 6, 2019. $25 million in prior funding for the Bella Vista Bypass via a Better Utilizing Investments to Leverage Development grant was secured by U.S. House members from Southwest Missouri and Northwest Arkansas in December 2018. Some updates will be made to the design plans before bids for construction are taken.44

It is anticipated that a contract will be awarded for construction of the I-49 Missouri-Arkansas Connector in Spring 2020. Work will extend into 2022.

U.S. 167 was upgraded to a divided highway from Lafayette and Opelousas by the 1970s. It was incorporated into the initial stretch of Interstate 49, which started in April 1980 with an $11.9-million contract for work in St. Landry Parish.35

One of the final segments of Interstate 49 built in Louisiana was the northernmost portion between Louisiana 3132 (Inner Loop Expressway) and Interstate 20 in Shreveport. This was completed by late 1994.

Lafayette to Shreveport

Interstate 49 was first proposed by Governor John McKeithen as the tolled North-South Expressway in 1965.32 AASHTO approved the initial route of Interstate 49 between Interstate 20 in Shreveport and U.S. 190 at Opelousas on July 6, 1977. Work commenced on I-49 in Louisiana in April 1980, and the first portion opened was a six-mile segment from U.S. 190 east of Opelousas in September 1983.32 An 18-mile section of I-49 was dedicated on October 13, 1987 within Natchitoches Parish between Louisiana 174 and Louisiana 6.33 That was followed by the completion on March 1, 1989, of a nine mile link in DeSoto Parish, from LA 175 to LA 509.33 Another 35 miles debuted to travelers between Washington and Meeker on May 15, 1989, a few weeks beyond the planned April 22nd opening.34

Work progressed with the opening of another 30 miles of Interstate 49 on November 22, 1989. This section included 18 miles from LA 174 to U.S. 84 in DeSoto Parish and 12 miles from Fierson to LA 526 (Industrial Loop) on the south side of Shreveport.35 Another 7.3 miles of I-49 opened around Boyce to the north of Alexandria on September 26, 1991.36 A movement during that time period shifted the alignment of I-49 from a bypass of Alexandria to a route through Downtown at the urging of merchants, civic leaders and political officials who feared economic losses for the city had it been bypassed. This pushed back the timetable for completion of the 4.5-mile segment through Alexandria to 1996.36 The section through Alexandria was eventually designated the Martin Luther King, Jr. Highway.

Additional stretches of the original Interstate 49 in Louisiana were dedicated by Governor Edwin Edwards on May 14, 1992 at the U.S. 167 interchange south of Alexandria. The ceremony preceded the opening of a 20-mile section of I-49 between Alexandria and Meeker and a four-mile segment from England Drive to Rapides Station. The 201 miles opened at the time totaled $598 million in costs.37

The 208-mile section of I-49 between Interstate 10 and I-20 in Louisiana was completed on May 1, 1996, at a cost of approximately $1.38 billion. I-49 was constructed with federal funds, some of which were redirected from unconstructed urban Interstates within Louisiana, and the rest (153 miles) originated from a “supplemental reserve.” At the time, Interstate 49 was the longest Interstate to begin and end within the same state.10

Louisiana: Interstate 49 South

Interstate 49 through Lafayette received initial approval on January 8, 2003 by the Federal Highway Administration. The motion allowed for funding to commence on the planned five-mile, $350 million viaduct between Interstate 10 and Lafayette Regional Airport (LFT). Not all residents were thrilled with this progress, as many near the projected path of the freeway feared impacts to developed and mostly poor neighborhoods nearby. In related opposition, legal action was pursued to move the project eastward into Saint Martin Parish. However, planners contended that the project complied with all applicable laws, and it appeared very unlikely that the highway would be relocated from the original planned routing.2

A Congressional group met in 2003 at New Orleans International Airport (MSY) to discuss the estimated $4.9-billion corridor and funding related issues. Representative Tom Pitre of Wisconsin indicated that the House was drafting a $375 billion, six-year proposal that would allocate Louisiana $4.28 billion to help pay for Interstate 49 within the state. On the docket for I-49 in Louisiana was the creation of a 36-mile portion of freeway between Shreveport and the Arkansas state line, and the upgrade of U.S. 90 between Lafayette and New Orleans to Interstate standards. Total costs within Louisiana were estimated to be $2.3 billion, with the state covering 20% of the expense.3

A number of projects have upgraded U.S. 90 to freeway standards in Iberia and Lafayette Parishes. These include an $24.5-million interchange at Louisiana 25 opened in January 2011. An upgrade of U.S. 90, from Pinhook Road to Broussard, was completed in October 2012 at a cost of $20 million. Frontage roads were constructed along the US highway between LA 675 and LA 88 at a cost of $21.4 million. These were completed in January and June 2011 respectively. Additional frontage roads were added to U.S. 90 from LA 83 to Darnell Road ($5.4 million and finished in February 2012), from Darnell Road to LA 85 ($5.8 million and finished in April 2014) and at Captain Cade Road ($1.4 million and complete in August 2012).

Louisiana: Interstate 49 North

Interstate 49 North is broken into 11 segments at a total cost of $670 million:28

  • A – Louisiana 168 to the Arkansas line
  • B – Parish Road 16 (Mira-Myrtis Road) to Louisiana 168
  • C – Louisiana 2 to Parish Road 16 (Mira-Myrtis Road)
  • D – U.S. 71 (south of Hosston) to Louisiana 2
  • E – Louisiana 170 to U.S. 71 (south of Hosston)
  • F – Louisiana 530 to Louisiana 170
  • G – Louisiana 169 to Louisiana 530
  • H – Louisiana 173 to Louisiana 169
  • I – Louisiana 1 to Louisiana 173
  • J – Louisiana 3194 (Dr. Martin Luther King Drive) to Louisiana 1
  • K – Interstate 220 to Louisiana 3194 (Dr. Martin Luther King Drive)

Groundbreaking for the first phase (Segment B) of the new Interstate 49 corridor, between Interstate 220 and the Arkansas State Line, occurred north of Mira at the intersection of Parish Road 16 and Parish Road 25 on Thursday, April 7, 2005.8 This section of Interstate 49 was estimated to cost $385 million.9 Work continued in 2007 on I-49 at the state line, where crews completed earth moving on a 6.6-mile long section.

State money was secured to bridge the 20% funding gap needed for I-49 North, allowing LADOTD to work on seven of 11 proposed freeway segments between Interstate 220 and the state border. Optimistic officials at the time hoped to see new 6.6-mile section of future Interstate 49 open in 2010, if not 2009.9

LADOTD later anticipated having most of Interstate 49 North, from Louisiana 1 (Segment I) to Louisiana 168 south of the Arkansas state line (Segment A), open and signed as I-49 by November 2013.25 This included a temporary end at Louisiana 168 that awaited completion of the Arkansas section from AR 549 southward, which was projected for May 2014. Widening of LA 168 east from Future I-49 to U.S. 71 was proposed to augment the connection to Arkansas until the freeways were seamlessly linked. The gap between LA 168 and U.S. 71 north of Kiblah, Arkansas opened to traffic after a ribbon cutting ceremony held by officials from both states on the morning of November 10, 2014.28


Interstate 49 in southwest Arkansas overtook the Arkansas 549 freeway between Exit 4 (U.S. 71) near Doddridge and U.S. 59 & 71 north of McKinney Bayou and Texarkana, as well as Future Interstate 130 along Arkansas 245. The first segment of this freeway (from Fouke to Texarkana) was completed on December 16, 2004.7 The remainder south to Louisiana opened on November 10, 2014.

Work in Texarkana focused on upgrading the Arkansas 245 freeway to Interstate standards from the interchange with AR 549, southeast of Texarkana, to Arkansas Boulevard, where I-49 branches northeast to Interstate 30 along a new alignment. A ribbon-cutting ceremony was held on April 30, 2013 for the 10.6-mile segment of new I-49 between Arkansas Boulevard and the Texas state line north of Texarkana. Wet weather delayed opening of the roadway to May 15.23

The Arkansas State Highway and Transportation Department (AHTD) is currently reviewing funding options for Interstate 49 between Texarkana north to Fort Smith. Currently no freeway route exists between Texarkana and Fort Chaffee, southeast of Fort Smith. Work commenced in 2010 on a section of Future Interstate 49 between County Route 8 and Arkansas 22 in the Fort Smith / Fort Chaffee area. 2.7 miles of roadway embankment, two overpasses and four box culverts for the new freeway were completed in fall of 2011.19 Additional work on the Chaffee Crossing section of I-49 added an interchange at Arkansas 22 (Rogers Avenue) and diamond interchanges at Massard Road and Roberts Boulevard as part of the overall $57.65-million, seven-mile stretch of freeway. The contract involving construction of 0.635-miles of roadway and the new interchange with U.S. 71 at the south end was let May 2, 2012.21 This work concluded on July 14, 2015.30 See a set of photos from the ribbon cutting ceremony held that day at David Backlin’s Flickr page.

Leading north from Fort Smith to the Bella Vista bypass, Interstate 540 (built as Arkansas 540) was redesignated as Interstate 49 per approval by AASHTO on October 21, 2013. A 30-day project to resign I-540 & U.S. 71 as I-49, between I-40 and U.S. 71 Business south of Bella Vista, kicked off on April 21, 2014. Signs on other future sections of I-49, including the Bella Vista Bypass and the stretch between U.S. 71 and AR 22 are dually signed as Future I-49 and Arkansas 549.26

What was previously known as Arkansas 540 was initially submitted to AASHTO for inclusion in the Interstate Highway System as Interstate 49 from Interstate 40 near Fort Smith north to the junction with Business U.S. 71 near Fayetteville. On April 25, 1997, AASHTO denied this proposal, indicating that the lack of connecting routes at the northern end would preclude the route from consideration at that time. It was approved as Interstate 540 a few months later by AASHTO, on November 14, 1997.

The Bella Vista Bypass, expected to cost $150.6 million,27 was planned to be constructed as a toll road. This concept was approved by the Arkansas State Highway Commission on April 12, 2006.11 A 3.03-mile section of the Bella Vista Bypass was let in February 2011 with ground breaking on July 8, 2011. This work covered a stretch of roadway between Arkansas 72 west of Hiwasse and Arkansas 72 southeast of Hiwasse.20 Work on the $19.8-million contract wrapped up on April 22, 2014.27


The AASHTO Highways Special Committee on U.S. Route Numbering meeting of October 14, 2011 approved the Interstate 49 designation in Missouri contingent on the route being fully upgraded to Interstate standards between Pineville and Kansas City. Additionally business loop designations for U.S. 71 at Butler, Joplin, Neosho and Nevada were given conditional approval for renumbering as Business Loops for I-49.

The Missouri Department of Transportation (MoDOT) approved highway construction on August 4, 2010 on a number of projects to upgrade U.S. 71 between Joplin and Kansas City to Interstate standards in anticipation of redesignating the highway to I-49 by December 2012.3 Four interchanges were completed at a cost between $4 and 5 million along U.S. 71 by September 2010. These included those at Missouri 126, Routes DD & EE and Routes V & C within Barton County, and Missouri 52 in Bates County.13 An interchange between U.S. 71 and Route E, north of Milo, opened to traffic on November 18, 2011.14 Work on an interchange between U.S. 71 and Route TT, midway between Horton and Rich Hill, commenced in late January 2012 at a cost of $6.4-million with a planned completion by December 2012.15 Further north, work continued with the opening of the overpass for 327th Street on August 9, 2012 near Archie. This bridge eliminated an at-grade crossing, and was the first of three projects to upgrade U.S. 71 to limited access standards locally. A diamond interchange with 307th Street and an overpass for 283rd Street opened later in 2012.18

A contract to erect signs with space allocated for Interstate 49 was let in October 2011 in anticipation of planned signing of the route statewide in December 2012. The project to install around 1,200 signs for I-49 commenced on February 1, 2012 at a cost of $3.5-million. That work was projected for completion by December 1, 2012.16 Interstate 49 was made official in Missouri on December 12, 2012 in a ceremony held at Joplin East Middle School at noon. The designation applied to 180 miles of U.S. 71 between Kansas City and Joplin.

Bruce R. Watkins Drive – Kansas City

The first of two parkway sections along U.S. 71 (Bruce R. Watkins Drive) northbound through Kansas City, Missouri. Photo taken 11/03/16.

Within Kansas City, U.S. 71 follows a combination of freeway and parkway from the Three Trails Crossing Memorial Highway interchange with I-49, I-435 and I-470 north to the Alphabet Loop (I-70 and I-670) at Downtown Kansas City. Known as Bruce R. Watkins Drive and historically as the South Midtown Freeway, the limited access highway for U.S. 71 was constructed for nearly $300 million in phases from 1987 to October 2001.6

Origins of the roadway date back to the “Expressways – Greater Kansas City” document issued by the city in 1951. State engineers presented two alignments for the eventual route in 1964. The South Midtown Freeway roughly followed the current alignment of Bruce Watkins Drive while the Country Club Freeway aligned south to 47th Street, west to Charlotte Street and Frank A. Theis Park and south along Brookside Boulevard before curving back to the east.6

Community opposition arose by February 1965, with a focus on potential disruptions to neighborhood areas along the South Midtown Freeway route to the east. As many as 10,000 residents would be displaced with the freeway project, and with the state highway commission voting to move ahead with land acquisition from Bannister Road north to 63rd Street, area neighborhoods declined. Earthwork started in 1972, but a federal lawsuit filed in 1973 halted work, citing violations of civil rights, environmental and relocation rules. Three quarters of the right of way was already purchased by 1976 while the lawsuit dragged on until 1985. City, state and federal officials eventually compromised on a new design for U.S. 71 in 1982. The redesign called for a hybrid of freeway and parkway sections meant to minimize disruptions to area neighborhoods. The roadway was named after Bruce R. Watkins, a local civic leader and one time city councilman in 1986, six years after his death.6

The two parkway sections include signalized intersections at Gregory Boulevard, 59th and 55th Streets and several right in and right out movements. Thousands of bushes and trees, attractive landscaping and decorative bridges were incorporated into the route as part of the court decision in 1985.6 With the parkway design, it is unlikely that Bruce Watkins Drive will ever be incorporated into Interstate 49.

Future Southern Terminus – Interstate 10 – New Orleans, Louisiana
The end of Interstate 49 South as originally envisioned was the interchange where Interstate 10 and U.S. 90 Business (unsigned Interstate 910) come together near Downtown New Orleans. This end point is not entirely certain however, as funding woes have questioned whether or not building Interstate 49 east to New Orleans from the Boutte area is feasible financially. One proposal considered is to reroute Interstate 49 northeast along Interstate 310 and end it near the Jefferson Parish line.
See the Interstate 910 Louisiana guide for photos of the possible south end of Interstate 49 at I-10.
